You have lots of things wrong with this car and 95% is materials settings. I would remove the mod from here and research material settings again. Then upload it.

Your bump map is prob whats causing your wheels to flicker.

Your missing the chassis texture making the bottom white and also the window trims.

Your tires shine, they need a black specmapp.

Most of the car is using a white specmap when it needs to be changed to a grey one or darker. and to fix the shine far away problem you need to again change the specmapp to dark grey for the L1 and L2 parts.
